Artificial Ice Making.


production of artificial ice, for the
preservation of food in large cities
In New York for instance, there is
no longer any waste of fish, flesh,
fowl or fruit from heat or decay.
In all the packing houses, under
the vast freight depots at st Johns
Park, as we'll as the warehouse
near the markets, there is q con-
stant production of artificial ice,
which freezes all perishable food,
so that it can be kept any reason
able time until sold. During
the dog-days, turkeys and chick
ems are frozen as stiff as at any
time in midwinter. This artificial
ice is ever so much cheaper than
natural ice, because it can be man.
ufactured when required and does
not call for the labor of handling.
Ammonia is the principal ingredi-
ent used in it's manufacture. A
daily paper on this subject says:
"The artificial production of cold is,
of course, no new thing. AS far
back as 1924, Valance; in 1884,
Perkins, and twenty years later
Twining made experiments with a
view to producing ice by mechanic
al means. In 1855, Twining built
Il machine in Cleveland, Ohio, in
which, by the use of sulphuric ether
about ton of ice day was pro-
duced. In 1870 Carre made ice
making practical business by the
invention of his ammonia-absorp-
ton machine, which produced Il
great sensation at the Paris Exhi-
bition of 1867. Cares principle
remains to-day that Of the besJ
cold producing machines. Lique-
fed ammonia, the product of the
compression of gaseous ammonia
at low temperature, in evaporat-
ing and returning to it's gaseous
state requires an immense heat
and will take it from any surround
ing material. The problem, there
fore, was to compress the gas un-
til it liGuiied, and then carry the
liquid ammonia to some place
where it's evaporation would alb
sorb heat not wanted. Thus, if ice
was desired, the liquid ammonia
could be carried into coil of pipe
placed in a tank of water. If cold
air simply was desired, pipe cary
ing liquid ammonia, or any SUBJ
stance cooled by the ammonia
could be carried to the apartment
which it was desired to cool Cares
first machine was simply strong
pump which compressed the gas
eous ammonia to the point of lique-
faction, and a series of pipes or re-
torts into which the liquid ammon-
ia was forced. Having absorbed
the surrounding cold by its expan-
sion, the gas was returned to the
compression pumps and reduced
again to liquid ammonia. All
improvements upon the system of
Carre and Twining have been
made chiefly in the line of greater
mechanical perfection of the con-
dension and expansion devices. A
perfect machine would lose no gas
whatever, but would continue using
the same gas over and over again."
But there are other uses to which
the production of artificial ice can
be applied. In the years to come,
living in large cities during the
summer time will be rendered
more tolerable by the refrigeration
of private houses, as we'll as public
resorts, such as churches, places of
amusement, and enclosed heating
houses in winter time, can be used
to cool them during the heats of
summer. Living in tropical reg
ions also will be rendered more en-
durable when the cheap produc-
tion of artificial ice is better under
stood. In northern regions, we
live under cover, as u protection
against cold, and with these new
refrigerating agents, an inclosure
against the hot weather will he q
protection in those regions of the
earth that are near the equator
This manufactured ice is one of
the most beneflcient and useful in
ventions of modern times.-Trom
